摘要： A filter assembly includes a housing, a cover, and a filter element. The housing defines a pocket. The cover includes a bayonet sized to be received within the pocket. The bayonet defines an elongated opening. The filter element is sized to be received within the housing. The filter element includes a media pack and a filter shell coupled to the media pack. The filter shell includes a trunnion that is sized to be received within both the pocket and the elongated opening to interlock the cover and the filter element such that removal of the cover from the housing initiates removal of the filter element.

摘要： A method of manufacturing a media assembly comprises winding a filter media about a center axis into a media roll and cutting the media roll along at least two cut lines and into at least two media packs of at least two media assemblies. The media roll is cut along at least one plane that is parallel to the center axis.

摘要： A filtration system includes an air cleaner housing and a filter element. The air cleaner housing includes a base and a removable cover. At least one of the base or the cover defines a cavity and a protrusion extending into the cavity. The filter element is disposed within the cavity. The filter element includes a plurality of media blocks each including a pleated filter media. The plurality of media blocks are arranged in arch shapes of approximately equal inner radii. The plurality of media blocks are coupled to each other along opposing edges that extend along a pleat direction of the pleated filter media. The media blocks together define at least one void that extends along the protrusion. The protrusion occupies a portion of the void.

摘要： Embodiments described herein relate generally to filter assemblies that include filter elements with cross-channel flow having flat and/or folded arrangements for optimized functionality and performance. The filter assemblies may be formed (e.g., shaped, constructed, etc.) using a variety of shapes, angles, configurations, and materials to improve the filtration and cross-channel flow of fluid through the filter media. The filter media may implement a wide variety of patterns (e.g., repeating, origami, rounded, etc.), shapes (e.g., tetrahedral, rhombus, square), and construction (e.g., pleated, integrated, interdigitated, etc.).

摘要： An air cleaner system including a housing having a first housing end with an opening, a second housing end, and an inlet proximate the second housing end. The air cleaner system also includes a filter element removably installed within the housing through the opening, the filter element including filter media, a first endplate coupled to the filter media at a first filter end, an open second endplate coupled to the filter media at a second filter end, and an annular projection extending axially from the open second endplate, the annular projection sealing against the housing and creating an axial gap between the filter element and the housing.
